In this study, the investigators examined the capsule-IOL interaction including anterior and posterior capsule adhesion, contact between posterior capsule and the posterior edge of intraocular lense (IOL), configuration of capsular bend and the incidence of posterior capsular opacity (PCO) between high myopia eyes and emmetropia eyes.

Measures: Contact of the anterior and posterior lens capsule with the IOL optic surface was evaluated. Types of capsular bend were described at the last follow-up. The incidence of posterior capsular opacity (PCO) was evaluated.

Eyes with an AL of 26.00mm or more were recruited to the high myopia group.

Eyes with an AL of 22.00 to 25.00 mm were recruited to the emmetropia group.

Exclusion Criteria:

Preoperative exclusion criteria included diabetes, history of ocular surgery or inflammation, pupils could not be dilated over 7mm after mydriasis,

patients who could not be available for follow-up.
